Okay, so I'll try dissecting this bit.
Consciousness cannot be grasped or held on to, as it is pure spirit awareness and not material or not biologically produced. It is like attempting to grasp and hold on to air with your hand. The air knowingly exists but cannot be held on to. Similarly, consciousness knowingly exists and also cannot be held on to.
That's true, as much as that you cannot get a physical hold of an idea. I'd draw a parallel to the "world of ideas" from Ancient Greek beliefs. An idea is a concept.
The "Air knowingly exists" is weird. Air doesn't know it exists. We know it exists. And we can, in fact, capture it.It's pretty easy. An empty bottle is probably full of air, so put a cap on it, and...
Air permeates the entire atmosphere. Likewise consciousness permeates the entire human body and will never be located, although its center has a place of focus."
erm... yes, air is everywhere where there's air. And it's not everywhere. Air is substance. Again - it's a stupid example by the writer.
Anyway, the feeling of consciousness does, in fact, have a location... the brain. There's probably a specific location in brain which allows one to feel conscious. And it is intervined with the body, so much that we're aware of our body and surroundings (to a level).
Although I'm not sure, what precicely they mean by "consciousness", because they're overmystifying it. It means "Being aware of oneself and surroundings, therefore knowing of one's existence in the world", right?
SAYS WHO??? Who had consciousness before beings were born?
...formless, colorless and genderless. It is separate from your mind functions, as it never changes or alters. While your mind functions are in continual states of change.
Consciousness DEFINITELY changes. Y'know... "subconscious", "unconscious"... you're not aware of your surroundings, or maybe even not of your body, when you're asleep. You imagine the surroundings, when you sleep. So it's still intervined with the mind functions. Without senses to sense the physical world, you can't be aware of being in the physical world.
Mind is the palette containing an endless array of color. Thought, motivation, intent, feelings and emotions paint the color on the canvas of consciousness. But painting consciousness to fit the color of your thoughts does not alter consciousness. It simply becomes the visible picture you have created. Consciousness never interferes or objects to the color your unfettered free will chooses to paint it with. This is another pointer at the separation of mind and consciousness, although each depends upon the other to give it observable existence. Consciousness is your non-biological existent personality. It is who you are. The picture you paint upon it is your character.
Does that even mean anything? What did you read out from it? Anything other than utterly metaphoric descriptions which can mean anything and some strange claims?
Consciousness is the totally open and pure canvas of knowable eternity that is absolutely unrestricted. The canvas being absolutely empty points directly at its absolute purity.
Absolute purity... eternity... absolutely unrestricted... nice words. Really. Kinda soud nice but don't explain much about consciousness.
To appreciate that last sentence you may have to use your intuition and not your intellect."
See? Nothing scientific about it, they admit it. And the rest of the text follows the example of the "purity and other deep words" principle.
So I guess the consciousness they describe is the ability to feel oneself. The ego. And being aware of one's self. Once you die, there's nothing physical of yourself to be aware of... And if you want proof - you just try using strong psychedelic substances! You won't feel yourself, you'll feel the dissolving of your ego, or your "consciousness" into everything else.
The text is just written by a person who feels there's an unchangeable "self" at the bottom of it all. Once you shake that a little... not to mention it doesn't explain much, or back stuff up, it just makes claims. So I don't see much that needs to be disproven.
And it sounds like something frauds like to write, too, so whatever you do, don't send him any money or buy stuff.
All in all, though, you can believe what you want... the only thing we can definitely be sure of is that we exist in some form and that we can at least imagine things.
